Slovakia's first independent coinage came directly from the political rupture of March 1939, when the Nazi-backed Slovak State was declared just days before Germany dismembered the remainder of Czechoslovakia. The Slovenská národná banka was established almost simultaneously, and producing a distinct national coinage was an immediate priority — both for practical monetary reasons and to signal separation from Prague.

The nickel composition was retained from Czechoslovak practice, though supply of the metal would become increasingly constrained as German war procurement tightened control over strategic materials throughout the early 1940s.
